Believe it or not, before 1993 NASCAR officials used hand-timed stopwatches to determine who was the winner in a close race. A good example of a close race was the very first Daytona 500, which took three whole days for a winner to be announced! These days NASCAR makes use of sophisticated cameras and timers that can call a race almost immediately. It's a stunning feat of technological engineering!
Take a look at this infographic, which will show you just how impressive it is. You can look at how fast the cars were going, how close the difference between first and second place was, and how often certain drivers show up in a photo finish!
